I've posted a lot about the fun and games Market Maker Broker Dealers engage in....and I'm pretty agnostic about it all, it is what it is....the way the game is played. 

Fake orders, Icebergs, short attacks etc....imo all designed to trick the dumb money retail investing crowd and put them on the wrong side of the trades.  If some players are buying low and selling high, it follows that others are buying high and selling low.

Right now I'm looking at RVXCF and seeing:

200 lots bidding $2.51 

8,100 lots asking $2.68

Does that mean there there is only 20,000 shares that a buyer is looking for at $2.51?  It might, but it could be much higher.  Likewise does this mean someone is looking to sell 810,000 shares at $2.68?  Again, perhaps....but it could also be a fake.

Here's a link to the article for those who want to delve deeper.
